The salts and esters of stearic acid are called stearates. As its ester, stearic acid is one of the most common saturated fatty acids found in nature following palmitic acid. The triglyceride derived from three molecules of stearic acid is called stearin.roduction [edit]. Stearic acid is obtained from fats and oils by the saponification of the triglycerides using hot water (above 200 Â°C). The resulting mixture is then distilled. Commercial stearic acid is often a mixture of stearic and palmitic acids, although purified stearic acid is available.

Drug-eluting stents are metal stents that have been coated with a pharmacologic agent (drug) that is known to suppress restenosis: the reblocking or closing up of an artery after angioplasty due to excess tissue growth inside or at the edge of the stent.estenosis has a number of causes; it is a very complex process and the solution to its prevention is equally complex. Traditional bare-metal stents have restenosis rates of up to 25%; current 2nd and 3rd generation drug-eluting stents have reduced that rate to single digits.
